if your generating 9-10 psi at this rpm range....

its your secondary operation...not the primary turbo

 

i understand that so is that your way of saying it's the actuator?

 

let me be more specific....is there anyway to determine which solenoid will be causeing the issue, or do you have to check them all?

 

id check each solenoid operation related to secondaries first..

although prior to that id make sure its not a hose issue..

 

If you don't understand how the system works, you kind of have to check them all. But to give you a starting point, read my post in this thread. It starts you out at a point that kind of divides the problem in half by telling you if the second turbo is ready to come on (but doesn't), or if it isn't ready to come on (so it can't).

 

thanks that really helped out. after going to that site provided by LAracer (thanks great infor) i was assuming it to have something to do with the charge control, but i am definetly not a turbo expert. thanks for helping out, i'll prob pull my UIM tonight for a look see.

 

well.....removed the UIM and not a god damn thing was off. removed air box, and had a look see at the solenoids and averything was connected...i hate my car. i hate it with all my heart

 

Wastegate and Turbo Pre-Control Solenoids - where are the harness connections for these??

 

okay so im guessing that these harness connection are the one under the UIM right behind the pressure chamber. fellas?

 

yep

between the chamber and the uim

first solenoid on the left... towards the ypipe side
